Counselors and their supervision. The counselors we propose to use in this intervention are licensed Ph.D. Clinical psychologists, who have served as counselors in the post-MI project and in the adolescent intervention project of the present program project. Supervision is carried out by Dr. Patrice Saab, Ph.D., who helped to develop both of our intervention protocols, and received supervisory training from the Beck Institute in conjunction with the ENRICHD trial and by Dr. Ronald Goldberg, M.D., who was the P.I. of the Miami site for the DPP. Based on weekly reviews of audiotaped sessions, Dr. Saab will determine, using a protocol check list, intervention adherence to the manual, point out any drift or lack of fidelity to the protocol and offer professional suggestions on how to remediate problems. Using standards developed in DPP, Dr. Goldberg will assure that counselors are adhering to protocol with regard to such issues as using a fat counter, weighing and measuring foods, using the food pyramid and supervising exercise and food diary homework. Weekly supervision is an institutionalized component of all of our intervention programs.
